About the WWU VNIRSD

The Western Washington University Vis-NIR Spectroscopy Database (VNIRSD) is an online tool for searching, graphing, and downloading publicly-available laboratory spectra. We have developed this tool to aid in our research group's analyses of hyper- and multi-spectral imaging data of planetary surfaces, and to share laboratory data acquired by WWU's Mars Spectroscopy Lab. We hope that this web tool will be a useful resource for other planetary researchers and the larger scientific community.

This is a beta version of the tool that has been made available to a limited subset of the Mars science community for testing. We want to hear from you if you have spectra to contribute or if you have ideas about how we can make the site more useful.

Want to contribute? Contact melissa.rice@wwu.edu.


The VNIRSD was created by:

The VNIRSD is based on an older tool developed by Kyle Mellander with significant input from Darian Dixon and students in the WWU Mars Lab.

If you use this database in your research, please cite the sources of spectra used. We would also appreciate that you acknowledge your use of the Western Washington University Vis-NIR Spectroscopy Database and link to this page [note to closed beta testers: don't link to this particular page, as it is unlikely to continue to exist!]

Individual spectra in the database are sourced from the data providers listed in the metadata of each spectrum and summarized below.
